Cutting out left turn makes a bigger difference in cities where turns are more frequent and often require waiting due to oncoming traffic. It saves fuel for UPS, else and for everyone who isn't waiting in a lane blocked by a UPS truck that is waiting to turn left. Now if we can just get others to stop turning left (when it requires blocking a lane). Since not all routes are in cities with dense traffic, not all routes will get the same benefit.
